The difference between US and German 2-year yields reflects expected policy differences between the Fed and the ECB. Overlaying it on EURUSD shows how closely the pair follows rate expectations.

How to build it:

• Get daily data for US 2-year and German 2-year yields.
• Calculate the spread (German minus US).
• Plot it against EURUSD on the same chart with two axes.

What it shows:

• Periods when EURUSD and the spread move together.
• Divergences, which may close over time.
• How quickly the relationship changes.

TradingView and other platforms allow custom spread symbols.

A practical refinement is to look at changes rather than levels: comparing the weekly change in the spread with the weekly change in EURUSD often shows the relationship more clearly than overlaying the two raw lines.

Have you built a yield spread overlay, and does it help your analysis?

Hello,

The 2-year yield spread between US Treasuries and German Bunds acts as the gravitational center for EUR/USD, cleanly isolating the market's forward-looking expectations for Federal Reserve and European Central Bank monetary policy. Because global capital inherently flows toward higher risk-adjusted returns, this specific duration is the perfect proxy: it strips out the term premium and inflation noise of the 10-year note, while avoiding the immediate-term anchoring of the 1-month or 3-month bills.

Overlaying this spread against the spot exchange rate provides a structural roadmap of the currency pair, but the true value lies in decoding what happens when the two lines refuse to cooperate.

Analyzing this relationship uncovers three distinct layers of market intelligence:

The "Lie Detector" for Spot Movements: If EUR/USD is rallying strongly but the yield spread is simultaneously widening in favor of the US dollar (US yields rising faster than German yields), the currency move is mathematically unbacked by interest rate fundamentals. These divergences often reveal that a rally is being driven by short-covering or speculative positioning rather than structural capital flows, making it highly vulnerable to a sharp reversal.

Macro Regime Identification: When EUR/USD and the spread track each other perfectly, it signals a market entirely fixated on central bank divergence. When the correlation breaks down completely, it is an immediate alert that a new macroeconomic driver has taken over—typically a major geopolitical event, an energy shock, or a flight to the safety of the US dollar during a liquidity crisis, where capital preservation temporarily overrides yield-seeking behavior.

Mean-Reversion Triggers: Currency markets can remain irrational, but they rarely ignore sovereign yield differentials forever. Extreme, prolonged divergences between the spot price and the 2-year spread frequently serve as a coiled spring, pointing toward the ultimate direction the gap will close.

Your refinement to track the weekly change (the delta) rather than the absolute level is the exact adjustment institutional quantitative desks use. Raw price and yield levels are non-stationary—overlaying them can create the illusion of correlation simply because both lines happened to trend downward over a five-year period. By first-differencing the data into weekly changes, you strip out the historical bias and isolate how the currency is reacting to shifting expectations at the margin. Markets do not trade on what the Fed or ECB has already done; they trade on the friction of changing expectations. Measuring the velocity of the spread against the velocity of the currency reveals exactly how aggressively the market is pricing in the next central bank move.

To make that concrete on TradingView, you can type the spread straight into the symbol box as an expression, something like TVC:DE02Y-TVC:US02Y, and it plots as its own line that can sit in a second pane under EURUSD. Daily data is enough, since intraday yield data on free feeds can be patchy. The German minus US version should rise when EURUSD rises if rate expectations are the driver. Two things help when reading it. Changes rather than levels, as you say, and marking the ECB and Fed meeting dates, because the relationship tends to reset around them as the market reprices. And when the correlation drops for a while, check what else is driving the pair, energy prices or risk sentiment for example, rather than assuming the gap has to close.
